How Data Centers and Central Offices Co-Exist in the Same Space

Craig CulwellCommScopeInside Plant Fiber Market Development

How Data Centers and Central Offices Co-Exist in the Same Space• Convergence of wireless and wireline will force the different work

groups to work together• Supporting the needs of the traditional CO and supporting the needs

of low latency data applications requires different mindsets, equipment and environments in the same facility

• Service providers need to support the “rip and replace” DC mindset while at the same time support evolving needs of the incoming OSP fiber cable infrastructure for a lifetime

How Data Centers and Central Offices Co-Exist in the Same SpaceToday we will examine• Why networks are converging and adding edge

data centers• The differences in the supporting infrastructures

for DC space in a CO• Power• Fire suppression• HVAC

• The differences in fiber cabling infrastructure

Converged networks can range from shared physical assets to fully integrated software & hardware platforms and more

Network convergence can be defined in many ways

Physical Spectrum Technology

Convergence delivers a competitive advantage by improving efficiency, agility, scale, and time-to-market

Convergence: The Merging of Wireless & WirelineStart from shared assets and work towards fully integrated systems

• Densification of the wireless network & fixed broadband deployments

• Leverage existing footprint and locations for multi-use, multi-service delivery

• Plan and build wireless/wireline simultaneously

• Common hardware for SDN/NFV• Applications run on COTS• Similar processes

• Network functions converge• Common credentials & policies• Containerization

Efficiency, agility, scale, and time-to-market all improve when networks and systems are converged.

The differences in the supporting infrastructures for DC space in a CO

• Power• Fire suppression• HVAC

Three Key Differences Between CO’s & DC’sEdge Data Centers are typically not large in scale

• Small – 1 to 8 cabinets 6kw-8kw per cabinet• Medium – 4 to 12 cabinets 8kw-12kw per cabinet• Large – 12 to 49 cabinets 12kw-14kw per cabinet

1. Electrical Code/Power• National Electrical Code exclusion for CO’s• CO: DC & battery plant DC: AC & UPS

2. Fire Protection• Exclusion for automatic fire sprinkler system for telecommunications NEBS compliant

CO space3. HVAC

• Typically DC equipment has a higher heat dissipation than telco equipment requiring additional cooling

• Fire suppressed areas must be isolated in case of fire suppression discharge

Deployment Options for DC Space at a CO• Self-Contained Pod/Container inside or outside a CO

• Cabinet-based structures that address the challenges of power, fire suppression and cooling

Deployment Options for DC Space at a CO• CO revitalized space carve out

• Building of a “Data Center” room within a CO separated by at least a 1 hour firewall

• DC space provides separate power, fire suppression and cooling

• Utilization of servers, switches, routers and such that meet at least NEBS Level 1 (-48 vDC powered) that can be deployed in a traditional CO space, but may require augmented cooling

The differences in fiber cabling infrastructure

DC Cabling Considerations

• CO’s expertise in singlemode fiber management and connectivity: SC & LC, simplex & duplex

• DC space introduces multimode cabling and connectivity including duplex LC, MPO-8, MPO-12 & MPO-24

DC Cabling Considerations• Plan for flexibility

• Use of multifiber push-on (MPO) connectors for fiber cables and patch cords makes it much easier and more cost-effective to change configurations when needed

• Panels that include modules that easily enable changes from LC to MPO and back to LC all while utilizing the same backbone cable

• Plan for density• Operators should choose the highest-density fiber platforms and switching equipment to allow

for future growth in connectivity for service delivery

• Plan for accessibility • Operators should use fiber panels and frames that maximize access to fiber connections
